Gut microbiota, dietary taurine, and fiber shift taurine homeostasis in adipose tissue of calorie-restricted mice to impact fat loss.

Previously, we demonstrated that caloric restriction (CR) stimulates the synthesis, conjugation, secretion, and deconjugation of taurine and bile acids in the intestine, as well as their reuptake. Given taurine's potent antiobesogenic properties, this study aimed to assess whether the CR-induced shift in taurine homeostasis contributes to adipose tissue loss. To verify that, male C57Bl/6 mice were subjected to 20% CR or ad libitum feeding, with variations in cage bedding and gut microbiota conditions.
